Hey HN, I made a site where you can draw on street-level panoramas. Your drawings persist and other people can see them in real time.
Strokes get projected onto the 3D panorama so they wrap around buildings and follow the geometry, not just a flat overlay. Uses WebGL2 for rendering, Mapillary for the street imagery.
The idea is for it to become a global canvas, anyone can leave a mark anywhere and others stumble onto it.
Cool idea !! But a limited number of places which is understandable :)
Cool idea, but of course the very first image I clicked into was a dick.
I recently learned that in Bhutan, they are sacred smybols since a long time
https://en.wikipedia.org/wiki/Phallus_paintings_in_Bhutan
Since I know that, I am rather amused every time I see a dick painted anywhere.
Haha yeah, can't have nice things I guess. I'm currently working on automated moderation to catch that stuff faster. In the meantime, Report button exists if you stumble into anything awful.
First thing I saw was a Swastika. It was painted on an ex Nazi building, but still...
A swastika or a Hakenkreuz?
Most people do not know about the directional-flip in these signs

Good fun thanks! Found a cute cat in Buenos Aires. It seems you have quite a lot of activity already, is that all from HN in the last two hours or from something else before this?
Mostly from HN in the last 2 hours, yeah. Had some early users before but nothing like this spike. Glad you found the cat drawing!
It's not very obvious which places are available for drawing. At first I thought it pulls Google street view, so I just zoomed in to some place I visited recently, but there was nothing.
So it turned out the spots on the map are actually the available panoramas, and not just a heatmap of the signatures.
Cool idea overall!
how long did this take to ship?
How do you draw something? I can't seem to do anything but look, I even made an account. I went to look at the nearest locations to me with drawings but they all had nothing. I found the menu on the left side of the screen but that didn't do anything. To draw does it require becoming a paying subscriber?
You should see a toolbar at the bottom with a pen/marker icon, tap either to start drawing. No payment needed, premium is really just to support the project.
A long, long time ago ... there was a browser extension or maybe an iframe, that allowed you to "comment" on public websites. Of course you weren't really commenting on the actual website, just some form of overlay. Anyway, it quickly devolved into lawsuits and rude comments if I recall correctly.
There have been several efforts. At one point the W3C were working on a standard protocol for it: https://www.w3.org/annotation/
Do you remember any details about the name of the software, or the cause of the lawsuits?
I had a similar idea, funny to hear it's been done and ended so badly.
I don't recall any lawsuits, but whytheluckystiff made one 20 years ago. https://ruby-talk.ruby-lang.narkive.com/buiXXTZh/what-is-hoo...
I believe it was https://web.hypothes.is/
Don't know if it matches with the lawsuits, but could've been Third Voice (1999-2001).

It is my belief that a time may come when we can all ‘write’ on, or link information to, any person, place, or thing, based on a melange of semantic anchors, and in that world there will be fewer secrets and more experts.
I used this one called "Gooey" in 1999 that let you have a realtime chat with people on the same page as you: https://www.cnet.com/tech/services-and-software/maker-of-goo...
Kinda fun, it'd be more fun to explore any street view
Digital/virtual graffiti. Just like in real life, you'll see good stuff and bad stuff.
Cool idea, but you should consider required auth to ban trolls.
On other hand, I wonder why many pictures are in the middle of the bridges or viaducts?
You may be right, I may need auth down the line. I wanted to reduce friction and let people draw right away though. I think the bridges thing is an artifact of Mapillary, the API I use for panoramas. Dashcams tend to overrepresent highways. Working on better curation.
Why are places marked which have zero strokes? Why is the heatmap activating for places without strokes? Is something going wrong?
Yeah, I see that does seem confusing. The heatmap currently shows all available locations, not just ones with strokes. I need to think through the UX more like trying to balance showing coverage with making it obvious where actual drawings are. Thanks for the feedback!
I love it until fine I'll signup and love it again but then no you pay now. My 2 cents is all I have to give.
I hear you on the friction. I’m experimenting with the 'ink' limits right now, also the ink actually regenerates. I think I need to make it more obvious in the UI
I was definitely finding it fun, responsive etc. Started to do a Simpsons-esque tag in Boston but ran out of credit. Hope to see more leeway keep up the good work

This is a really cool concept.
I like the idea of turning the map into a kind of shared canvas. The fact that the strokes wrap around the 3D geometry instead of just being a flat overlay is a really nice touch.
Curious — how do you handle moderation or prevent drawings from turning into spam once more people start using it?
Thanks! There's a report button if you hold on any drawing, plus I have admin tools to delete flagged stuff. Working on automated moderation to catch things faster as it scales
Nearly certain you're responding to an LLM
How are the panoramas chosen? That is, can I select one that isn't currently on the map?
About 2,000 locations so far. Mapillary has a lot of imagery but finding the 360 panoramas is trickier since they are a lot rarer. I'm actively expanding coverage
good work! this is like Wplace but in 3D
Thanks! That was the main inspiration.
Ok, I give up.
How am I supposed to draw something?
Sorry about that, just upgraded the infra. Try reloading the page!
I might be missing something obvious but there only appears to be the option to draw something in predefined places - where the bubbles appear on the map.
I'm trying to mark up somewhere new that doesn't have a bubble and I can't see how I'm supposed to do that.

Nice but come on paying 3.99 for more ink. You HP?
the happy face on the sun lmaoooo
